A MAURICE MATHY, 0F LIEGE, BELGIUM.

To all whom it may concern Be it known that I, MAURICE MATHY, a subject ofthe King of Belgium, land resil dent of Liege, inthe Kingdom of Belgium, have'invented certain new and useful Improvements in and Relating to Coke-Ovens;

and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or Hgures of reference marked therein, which form a part of this specification.

This invention relates to improvements in coke ovens having means for recovering the by-products.

According to the present invention the retort is heated by surface combustion methods.

This result is realized by providing beneath each retort a passage in which the mixture of air and gas takes place, said mixture then penetrating into various vertical Hues arranged in the jamb columns of the retort filled with porous and Hreproof material. The hot gas released from the upper part of these Hues is brought by other like Hues, but which are not filled with porous material, into a recuperator serving for heating air and and gas or only one of these Huids. Two recuperators of this kind are arranged under each retort.

The invention is more particularly described with reference to the accompanying drawings showing as an example a form of construction in the case of a recuperator which only heats air.

Figure 1 is a transverse section of the bed or brick work in the axis of the retort.

Fig. 2 is a section on the line A B of Fig. 1.

Fig. 3 is a section on the line I J K L of Fig. 2.

Fig. 4 is a section on the line C D of Fig. 1.

Fig. 5 is a horizontal section on the line E F of Fig. 4.

Fig. 6 is a horizontal section on the line G I-I of Fig. 2.

Beneath each retort 1 a pair of suitable recuperators 2 is arranged: in the the form of construction illustrated earthenware or Hreclay recupertors are used. Each of these coins-OVEN.

recuperators receives hot gas from Vone-'half of the retort and heats the air for this portion of the retort. Y In the j ambcolumnson each side ofan extending over one-half of the retort, vertical Hues 3 and 4 are arranged. v

The Hues 3, that is to say, thosev on the side of the: masonry face, are filled with porous and refractory material and serve for heating the retort.

-The Hues 4, that is to say, those arranged toward the center of the foundation or brick work, serve for conveying the gases of combustion to the recuperator.

All the Hues 3 and 4 of the same half retort situated in the same jamb are connected at their upper part by a common horizontal Hue 5. At their lower part the Hues 3 end in a horizontal Hue 6, while the Hues 4 end in avertical Hue 7. (See particularly Fig. 6.)

This Hue 7 communicates with a Hue 22 conveying the hot gas to the recuperator 2. Beneath the bed of each retort are arranged two superimposed passages 8 and 9.

The first passage 8 is fed with gas by the pipe 10. The second passage 9 is fed with hot air by the vertical passages 11l connecting with a passage 12 receiving hot air from the recuperator 2.

At the sides of the passages 8 and 9, other passages 13 and 14 communicating with the passages 8 and 9 by vertical slots 15 and 19, are arranged, and these passages 8 and 9 are preferably constructed by means of Hreclay or Hrebrick elements.

The passages 13 and 14 communicate lwithv the Hues 6 and are'like them and like the vertical Hues 3, Hlled with porous and refractory material.

Cold air from a pipe 16 is conveyed for each retort by a pipe 17 into a chamber 18 from which it passes into the recuperator 2. After having been heated in this recuperator it penetrates into the 'passage 12 and goes by the various passages 11 into the passage 9. It Hows through the various vertical slots 19 in this passage and encounters in the passages 13 and 14 in the center of the mass of porous and refractory material which is found there the gas emerging from the vertical slots 15 of the passage 8.

It is preferable that the slots 15 and 19 ending at a common passage 18 or 14 shall not be in the same vertical plane but be staggeredrelatively to one another.

The mixture of gas and air Which is there produced ignites and enters the 'iiues y6 and then passes into the vertical iiues 3, thus causing the heating of the retort. v v ne hotlgas which is discharged from the upper part of theiiues' is collected in the lue 5. It then passes `intothe vertical lues 4 and is led by the flue 22 to the recuperator 2. After havlng heated the air brought into this recuperator it is conveyed by a. channel 20 to the gallery 21. r

Hav-ing vnow Vparticularly described and ascertained the nature lofthe vsaid'invention and in what manner the same V.iscto be performed, I declare that vkwhat I claim is A .coke ovenilcomprsing retorts, lues on each side of said retorts, filled with porous n and refractory materials a pair of parallel Npassages arranged under each retort for air andgas respectively, and Iparallel yducts on the side of said passages, led with porous ,andrefractory materials and communicating on the one hand With the flue and on the other hand Withzthe parallelfpassages l In v:testimony WhereofI aix my signature in `presenceof two Witnesses. n Y MAURICE `MATHY. n
